Working 14 hours a day until you're 55 and missing your kids growing up is not what I would consider a recipe for happiness.

Writers and journalists tend to be simplistic about politics when, like all other areas of life, it's more complicated.

Writers of fiction should stick to writing, not pop up on panel shows or as a talking head.

You can't ever win the war on crime, or the war on terror. You can't repeal human nature.

You find out what you think by talking to yourself.

Cut your manuscript ruthlessly but never throw anything away: it's amazing how often a discarded scene or description, which wouldn't fit in one place, will work perfectly later.

First comes an idea. Then, characters begin to evolve out of the landscape of that idea. And then, finally, characters dominate: plot is simply a function of what these people might do or be. Everything has to flow from their personalities; otherwise it will not be emotionally engaging, or plausible.

For me, as I suspect for most people, there comes a point where you have enough. If you've got £20 million, why keep going until you've got £100 million or £1,000 million? Does anyone need another vast yacht or private jet or a house full of gold?

Having the urge to write a novel, especially if you've yet to be published, is like having a medical condition impossible to mention in polite company - it's a relief simply to know there are fellow-sufferers out there.

Humans have changed little over time. We think we've invented the modern world but they were making better speeches 2,000 years ago and grappling with issues of empire and terrorism.

I am sure future historians will say the biggest and most astonishing change in politics has been the embracing of all the tenets of Thatcherism by the party of Keir Hardie: trade union legislation, Europe, the replacement of Trident, 10 per cent tax for people who have made millions from their companies.

I can't get very excited about the House of Commons these days because I don't feel the power is there. What is really bizarre is that you sense it is not in Washington either. It is now very hard even to locate the levers of power, let alone to pull them and change things.

I like to take people you wouldn't really think people would write novels about: an aqueduct engineer, a code-breaker, a hedge-fund manager. It's in those sorts of lives that I find more fascination than in a CIA operative or a Marine or something like that.

I see myself as the literary equivalent of a skilled lathe-operator, or a basket-weaver; a potter, maybe: I make mildly diverting objects that people want to buy.

I think a lot of us feel, when we look at the Dow Jones plunging, alienated - you do feel as if we're in the grip of some alien force that slipped human control.

I used to love politics. I can't say I do any more. All the fun has gone out of it. Each side is engaged in this trench warfare of managerialism. They're all too scared to say anything that might make them appear something other than completely bland.

If one tries to think about history, it seems to me - it's like looking at a range of mountains. And the first time you see them, they look one way. But then time changes, the pattern of light shifts. Maybe you've moved slightly, your perspective has changed. The mountains are the same, but they look very different.

It's easy enough to get into power. You can make promises and try to be all things to all people. But the moment you have to make decisions, you're going to annoy at least half of them. Whatever you do, in the end you're almost certain to be brought down by your own character traits.

Leaders today are isolated by phalanxes of body guards. It's profoundly undemocratic, the way they have used terrorism as a means to protect themselves.

My father left school at 14, my mother at 13. My father was clever and well-read. He took a newspaper, always watched the news, discussed it all the time.
